Change "from" in email

Hi All,

We have a user ABC who has certain cron jobs scheduled and for most of the cron jobs sending emails to group of people. User ABC has been replaced with xyz. Now we want to change the "from" to xyz instead of ABC. is there any way to change "from" other than scheduling the jobs under xyz.

Regards,
Inder

How is user ABC sending mail?
If he is using mutt, he could create the following file in his home directory:

> cat .muttrc
my_hdr From: xyz@emailADDY.com

having this file would cause all outgoing mutt mail to be associated with the new from user...
